Description

Cup transfer apparatus for vending machine

The present invention relates to a vending machine, and more particularly, to a cup transfer device of a vending machine for transferring a cup supplied by the cup supply device between the cup supply unit and the raw material discharge port of the vending machine.

1 shows a cup conveying apparatus 10 of a conventional vending machine. The cup conveying device 10 of the vending machine shown is the applicant's unpublished prior art and, therefore, cannot be cited as the basis for denying the inventive progress.

1, the cup conveying apparatus 10 of the conventional automatic vending machine is comprised including the cup holder 20 and the drive means 30. As shown in FIG. The cup holder 20 is formed with a cup support part 22 for receiving the cup 40 supplied by the cup supply device 50.

The drive means 30 comprises a motor 32 and a reducer 34. The rotational force of the motor 32 is amplified by the reducer 34 and then output through the rotation shaft 36. Thereby, the cup holder 20 fixed to the rotating shaft 36 rotates.

That is, in the cup conveying apparatus 10 of the conventional vending machine, when the rotating shaft 36 is rotated by the driving of the motor 32, the cup holder 20 fixed thereto is rotated so as to supply the cup feeding apparatus of the vending machine. The cup 40 is conveyed between 50 and the raw material outlet 60.

However, according to the cup conveying apparatus 10 of the conventional vending machine, there is a problem that no countermeasure is provided for an abnormal situation in which the cup holder 20 cannot be smoothly rotated.

This situation may occur when the cup 40 is disengaged from the cup support 22 or the posture of the cup 40 in the cup support 22 is poor, in which case it is not shown with the cup feeder 10. The cup 40 may be caught between an object that is not around.

In this case, if the motor 32 continues to operate, the cup transfer apparatus 10, the surrounding objects, or the motor 32 may be damaged. In addition, if the user's hand is inadvertently entered during the operation of the cup transfer device 10, the user may be injured.

Accordingly, an object of the present invention is to provide a cup conveying apparatus of a vending machine that prevents damage to a cup conveying apparatus or an object or a motor around, even when an abnormal situation occurs in which the cup holder cannot be rotated smoothly. have.

In addition, another object of the present invention is to provide a cup transfer device of a vending machine in which the safety of the user is guaranteed from the cup transfer device even if the user's hand enters during operation of the cup transfer device due to carelessness.

An object of the present invention as described above, the cup holder; Means for driving a cup holder; And means for selectively interrupting the power transmitted from the drive means to the cup holder.

In an embodiment of the present invention, the drive means has a motor and a rotating shaft driven by the motor; The cup holder is rotatably coupled about an axis of rotation; The power control means includes a first clutch disk coupled to the rotation shaft to enable axial movement, a second clutch disk fixed to the cup holder, and an elastic member for pressing the first clutch disk toward the second clutch disk. do.

In addition, the above object of the present invention, the motor; A rotating shaft driven by a motor; A cup holder rotatably coupled about an axis of rotation; A first clutch disk coupled to the rotary shaft to enable movement in the axial direction; A second clutch disk fixed to the cup holder; And a resilient member for urging the first clutch disk toward the second clutch disk, wherein the first clutch disk and the second clutch disk each have an uneven portion formed to be engaged with each other by an inclined surface. It is also achieved by providing a cup feeder.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 to 4 illustrate a cup conveying apparatus of a vending machine according to the present invention. According to this, the cup conveying apparatus 100 of the vending machine according to the present invention comprises a cup holder 120, a drive means 130 and a power control means 140.

The cup holder 120 is formed with a cup support 122 for receiving the cup 40. The drive means 130 includes a motor 132 and a reducer 134. The rotational force of the motor 132 is amplified by the reducer 134 and then output through the rotation shaft 136.

The cup holder 120 is rotatably coupled to the rotation shaft 136. Between the cup holder 120 and the rotating shaft 136 is interposed the power control means 140 for selectively transmitting the rotational movement of the rotating shaft 136 to the cup holder 120.

The power control unit 140 includes a pair of clutch disks 142 and 144. The first clutch disk 142 is coupled to the rotation shaft 136 so as to be movable in the axial direction, and as shown in FIGS. 2 and 3, an uneven portion 142a is formed on the upper surface thereof.

The first clutch disk 142 is biased upwards in the axial direction by the elastic member 146, and the rotation of the first clutch disk 142 about the rotation shaft 136 is prevented by the pin 148. Reference numeral 150 is a support plate for supporting the elastic member 146, 152 and 154 is a stop ring.

The second clutch disk 144 is integrally formed with the cup holder 120 on the lower surface of the cup holder 120. On the lower surface of the second clutch disk 144, as shown in FIGS. 2 and 3, an uneven portion 144a that is engaged with the uneven portion 142a of the first clutch disk 142 is formed.

The uneven portions 142a and 144a of the first and second clutch disks 142 and 144 have inclined surfaces 142b and 144b, respectively (FIG. 3), and the uneven portions 142a and the first portion of the first clutch disk 142 are formed. The uneven portions 144a of the two clutch discs 144 are engaged with each other by these inclined surfaces 142b and 142a.

The cup conveying apparatus 100 of the vending machine according to the present invention configured as described above, when the motor 132 is operated, the uneven portion 142a of the first clutch disk 142 and the uneven portion of the second clutch disk 144. The transmission of power takes place as the 144a mesh with each other (FIG. 4).

At this time, the elastic member 146, one end of which is supported by the support plate 150, presses the first clutch disk 142 toward the second clutch disk 144, and the pair of clutch disks 142 and 144 are applied by the pressing force. The transmission of power through) takes place continuously.

On the other hand, when an abnormal situation occurs in which the cup holder 120 cannot be smoothly rotated during the operation of the motor 132, the drive means 130 is driven from the drive means 130 to the cup holder 120. The transmitted power is cut off.

That is, when the rotation of the cup holder 120 is hindered due to some cause, as shown in FIG. 5, the uneven portion 142a of the first clutch disk 142 may apply the pressing force of the elastic member 146. The second clutch disc 144 is separated from the uneven portion 144a.

Therefore, the first clutch disc 142 and the second clutch disc 144 are not engaged with each other, and are idle. Accordingly, the first clutch disc 142 and the second clutch disc 144 are transferred from the driving means 130 to the cup holder 120 through the power control means 140. Power is cut off.

Therefore, according to the cup conveying apparatus 100 of the vending machine according to the present invention as described above, even when an abnormal situation occurs in which the cup holder 120 can not be rotated smoothly, the cup conveying apparatus 100 or the peripheral The damage of the object or the motor 132 and the like is prevented.

In addition, according to the cup conveying apparatus 100 of the vending machine according to the present invention as described above, even if the user's hand enters during operation of the cup conveying apparatus 100 due to carelessness, the user's safety from the cup conveying apparatus 100 This is guaranteed.

In the above, certain preferred embodiments of the present invention have been illustrated and described. However, the present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. will be.
